'To all who-m t may concer/ie' I Be it known that I, `An'rni'mH..Wiir'rw1in, a citizen ,of vthe `United States, residing at Rice Lake,inthe county ofv Barron, State of Wisconsin, have invented certain newand useful Improvements in Wrenches; and I do hereby declare the`following to be a full, clear, and exact description ofthe invention,such as will enable others skilled in the art lto which it appertains tomake and use the j same." l

l This invention relates to new and usefulv improvements in wrenches. jp y One object of the invention isto provide a wrench which is formedfrom the minimum number of'part's, which parts are simplek inyconstruction facture. j j j j Another object of the invention is to provvide a wrench wherein the lever which holds the movable jaw. in adjustedposition is so 2arranged that it is adapted to vbey gripped with theshank of the wrench, thereby securing against displacement of themovable jaw, while engaged with the work.

y Other objects and advantageswill beiap-l parent from theollowingdescription when taken in connection with the accompanyingdrawing; f

In the drawing-` u Figure 1 is a side elevation of a wrench made inaccordance with the invention.

Figure 2 is an edge view of the-wrench looking toward the open side ofthe groove.

Fi 'urey 3 is a vertical longitudinal secytiona `view taken centrallythrough the v14 of the movable jaw 15, the outer end of vsaid bar-.beingformedv with al transverse vand cheap. to manuv,

' notch 16, for the reception of the transverse pin 17 disposedV in theouter end of the channel13. 'I his pin limits the outward slidingmovement of the' movable jaw 15, as will be understood. On the lowerface of the bar 14 there are formed the series of teethv18.

Formed longitudinally in one edge of the handle 'shank 10, and extendingvfrom* the end of the channel 13 which lies beneath the stationary jaw12, to a point-adjacent the otlierend of the shank,is a groove 19, and

pivotedly 'mounted within this groove, directly beneath the stationaryjaw 12, is .a

lever 20, the pivotal'end of lwhich is formed with a series ol' teethill-,adapted to yengage .with ,the teeth 18 when the lever is swung intothe Vgroove 19. A portion of the pivotal end of the lever 2Oremainswithout the up- `per. end oit theshank 10 and in lthe oppositefaces' of this portion of the lever there are formed fingerV receivingynotches 22,*within which the fingers of the operator are to be placed.to swing the lever in and out of the groove 19. y y v,

Whenthe lever 20 is disposed within the groove 19, and the movable jaw15 has been properly adjusted to cooperate with the jaw 12, tofgrip thework, the operators hand will grasp the shank 10 together with the lever20, thus firmlyr holding the lever within the groove, and maintainingtheyteeth of [the lever in proper engagement with the teeth of the jaw15. To adjustthe jaw Ait is only necessary toswing the lever 20 out ofthe groovey 19, then slide the jaw 15, to the proper position along thethe groove or channel 13, after which the lever' 20v is again swung intothe groove 19, to engage its teeth with those of the jaw 15,

The outer free endyoty the lever A20 is formed with a screw-driverypoint 20.

What is claimed is: Y A wrench comprising a shank having a head on oneendy formed with a stationary jaw, said. shank having a longitudinalgroove formed vin one of the narrow faces thereof, saidgroove'beingenlarged at one f end and entering the stationary jaw, achannel formed longitudinallyin the outer tace of the head, Said channelnterceptng the enlarged end of the groove at an angle thereto, a movablejaw sldable n'sad channel7 :1nd a tapered lever movably supported in thegroove of the shank. the lower face of vthe lever snugly ttng tbe bottomof the groove, the upper face of the lever being slightly above theedgesrof the groove to be gripped with the Shank to engage the leverwith the movable jaw.

In testimony whereof, have affixed my signature, in the presence of twoWitnesses.
